Title: Systeme et procede de nettoyage par un fluide pour des buses d'impression par jet d'encre fonctionnant en continu
Inventor: PAROFF PAUL J
IPC: B41J2/165
Filed: 1996-04-09
Granted: 2006-09-12
Abstract: On utilise un fluide (de l'eau ou un autre liquide) (46) pour laver la surface avant d'une cartouche d'impression (17) par jet d'encre. Une plaque (24) à buses recouvre le système de buses (23) et le protège des éclaboussures d'encre (32). Dans les imprimantes par jet d'encre, les gouttelettes d'encre sont propulsées par une pluralité d'orifices dans la plaque à buses de la tête d'impression. Durant l'éjection des gouttelettes d'encre, l'encre pulvérisée se dépose autour des orifices. Les gouttelettes d'encre sont déposées sur une bande de papier (14) jouxtant la buse et le brouillard des gouttelettes dérive en arrière pour se déposer sur la face de la plaque à buses. Une partie de l'encre s'infiltre derrière la plaque (24) à buses sur le système d'orifices (23) des buses. Le revêtement d'encre attire des particules ayant tendance à obstruer les orifices des buses. Le revêtement d'encre est lavé par les flux (46) de fluide qui balaient la surface à buses et, dans certaines formes d'exécution, les orifices des buses. Le fluide (46) peut être de l'eau, de l'encre ou un autre liquide dont le flux est dirigé le long de la surface à buses. Egalement, le fluide peut être de l'air comprimé soufflé le long de la surface à buses.

Abstract: A business form with labels, and a method of construction of the form, are provided. The form according to the invention includes a cellulose ply larger than a second, release liner ply, and the release liner ply may be provided so that one edge (e.g. with tractor drive holes therein) extends past a substantially parallel edge of the cellulose ply, and at the opposite edge of the release liner ply, adhesive release material is provided along between 10-50% of the length of the edge so that the release material covered portion of the edge is not substantially permanently adhered to the edge by the adhesive between the plies. This allows the labels die cut (or otherwise formed) in the cellulose ply, where overlapped by the release liner, to be removed from the back or the front, and also allows one to separate the release liner ply completely from the cellulose ply, if desired (after use) for ease of recycling since one can get a port ion started which allows breaking of the "permanent" bond between the cellulose and the release liner where no release material is provided on the release liner.

Abstract: A waveguide element is capable of realizing acute waveguide discontinuity,  such as a right angle bending, (L-shaped bending) or branching (T-shaped branching).  Two single mode waveguides having the identical cross-sectional structure form a waveguide discontinuity where center axes thereof extending in the longitudinal direction intersect with each other at an angle .theta. (0<.theta. ~ 90°).  A leaky wave propagation region in a form of a lozenge shape having a length of one edge of L is located in the vicinity of a point where the center axes extended in the longitudinal directions of respective incident side and side single mode waveguides,  with an effective propagation wavelength of a dominant mode there of to be cos (.theta./2) times of an effective propagation wavelength .lambda.G.  Thus, an energy of the wave launched from an incident end of the single mode waveguide can be efficiently taken out from a end of the single mode waveguide.

Abstract: The inventive method and the inventive device serve for liquefaction of slud gy to compact sediments (3) in vessels (1) in which crude oil (2) is stored and/or transported, whereby a liquid is injected above the sediment surface via nozzles (11) under the effect of which liquid the sediment (3) is at least partly liquefied or dissolved in the liquid such that it can be removed from the vessel (1) together with the liquid. For this purpose a substantially horizontally flowing liquid current which is possibly closed in itself is created above the sediment surface by directing the injection through all nozzles (1 1) such that the injection direction has a horizontal component which is orientated tangentially to a current line of the liquid current to be create d and is orientated in flowing direction. The injected liquid is crude oil or a refinery product and differs from the lowest levels above the sediment in that it comprises a smaller share of heavy components.

Abstract: A method of producing an instrument face having functional indicia thereon (such as a clock face dial, thermometer face, etc.), allows high quality, multicolor instrument faces to be produced in a cost effective manner even for small runs (e.g. 1-500 units). The instrument face is created in a computer in electronic format, and the computer transmits electronic signals to a color photocopier, to control it to print the instrument face on a sheet of paper. Thesheet of paper may be laminated to a more rigid sheet, e.g. styrene, cardboard, acrylic or plexiglass, and then an instrument face of the appropriate geometric shape and size is cut from the sheet material. The face is assembled with other functional components to produce an operable instrument. The cutting is preferably practiced automatically utilizing a laser cutter under the control of the computer. A scanner or CD ROM may be utilized for inputting data into the computer. A simplified version may be practiced by overlaying a transparency with instrument dial indicia on a color photograph, and color photocopying it, then laminating, cutting, and assembling it into an instrument.
